Dairymaster ACR ram plunger assembly The Dairymaster ACR ram plunger assembly is a crucial internal component of the Automatic Cluster Removal (ACR) system. It controls the vacuum pressure within the ram mechanism, allowing for precise attachment and timely removal of milking clusters during the milking process. The plunger assembly includes the plunger, seals, and related components that work together to regulate vacuum flow smoothly and efficiently. This ensures milking clusters are removed automatically once milking is complete, improving cow comfort and milking efficiency. Made from durable materials suited to the harsh dairy environment, the assembly requires regular maintenance and replacement to maintain optimal system performance. Genuine Dairymaster parts ensure reliability and long-lasting service. CR118
